Should the industry be alarmed at the potential degradation susceptibility of tunnel oxide passivated contact (TOPCon) solar cells? Or are the problems easily addressed and more a reflection of rushed-to-market products? pv magazine contributor and consultant Götz Fischbeck reports.
Scientists in Norway used various imaging and characterization techniques to analyze the cells and other components of silicon PV modules that had been installed in the field for more than 10 years. The group’s aim was to isolate the role of moisture in various mechanisms that cause performance loss over time, and to understand how these mechanisms progress over long-term installation in real outdoor conditions.
New entrants to solar equipment procurement may be surprised to encounter constantly amended contract terms, index-linked price rises, and near-worthless defect warranties, but they reflect recent supply chain troubles. Clean Energy Associates’ Martin Deak offers a buyers guide.
Scientists in Austria have examined the impact of different backsheet and encapsulant material combinations on module performance and degradation. This led them to develop a model to quantify the degradation rates of different materials, potentially helping manufacturers to identify better, longer-lasting materials for these vital module components.
Starting this year, ground-mounted solar modules in Germany can be replaced before the end of their service life, unlocking gigawatt-scale potential for new generation capacity without lengthy permitting processes or the need for new sites. Opinions differ as to what should happen with the decommissioned but still functioning modules, as pv magazine Deutschland’s Sandra Enkhardt reports.
This year’s edition of Solar Quality Summit Europe started on Jan. 24 in Barcelona, Spain. With Europe set to hit record solar installations in the coming years, industry stakeholders discussed how to do that quickly. Digitalization, monitoring, revamping, and technology audits were all on the agenda.
